I always wonder, if these deep sea creatures still have functioning eyes at these depths they must be ridiculously sensitive right? So would the intensity of the lights on the rovers be as bright for them as us staring at the sun?

[@leont.17]

Don't think so. Eyes aren't an evolutional advantage down there, so they will develop backwards to save energy. Animals down there are probably almost blind and have other senses developed. Compare it to moles, they are almost blind too and have no problem with day light. It just wouldnt make sense for a sea creature down there to have that sensitive eyes as other senses will take over

[@agamenonmarques4448]

I thought the same, I was uncomfortable seeing the camera flash in their eyes

[@rosiehawtrey]

Which is why most of the time they use red lights, enough for us to see, but not enough to harm the critters. White light only used for filming purposes.

[@saosaqii5807]

Which is also odd because normally evolution favors use it or lose it and there isn't enough light down there to even use it majority of the time so I would expect them to lose it But if it became more sensitive that's understandable too, but less if they simply enhance other senses and lost their eyes

[@gurgleblaster2282]

Interesting thing is that in so low temperatures many chemical reactions are slower or non existing. That would suggest that those creatures not only live longer but they are living slower. I bet that such a gigantic pressure also adds to this effect.

[@bern_stock8946]

If the aging is slower, then does this mean a reproductive cycle's length is larger? Then does this mean that they did not undergo too much of an evolution? Then does this mean that birth of life on earth can be traced back from them, cuz you know the should've survived meteors and stuff? Then are the prehistoric?

"Gravity" is somewhat of an abstract concept when you can maintain neutral buoyancy in your "atmosphere" (in this case: the ocean). It's easy to weigh a lot when you don't actually have to support all that weight _with your body._

buoyancy, i wonder how high can u reach into the skies and drop a nuke into the ocean, how deep it can penetrate before buoyancy affects it from going any deeper then detonates, whats the impact or reach the blast can go further down the ocean..i wonder if any of that is ever measured?... i assume a missile shot downwards in the ocean is no different to a submarine diving to the deepest depths that bouyancy and pressure stops it from continue to dive down?

When I was a child, my parents took me with them on a family vacation to Tahiti. In the airport, my dad got me a book from a newsstand that was an illustrated dictionary of sea creatures. Surprisingly, despite being a book meant for kids, that dictionary contained a vast array of ocean animals that most people have never even heard of. Both the Greenland shark and the vampire squid were in that book, and I still remember them from reading it all those years ago.

[@tamatebako_yt]

@@embreis2257 I wouldn't necessarily extrapolate from our experience to those of other creatures. You could say the same thing about a mole. Isn't it disgusted having to live below ground, eating worms all day, being almost blind? Does the mole say to itself every day: Oh I wish I was a rabbit above ground, I could eat green grass all day and see the sun shining? Probably not. A mole evolved to be that way, it doesn't know anything but that life, and it doesn't have the mental capacity to envision something different for itself. I don't think it is unhappy. Having said that, the Greenland shark probably could do without the parasites, even though it doesn't rely on eyesight all that much. Still, parasites suck.

The thing with the Greenland Shark is that they swim into freshwater to shake off the crustaceans - they've been found in the rivers of Quebec, having swam up the seaway to get there, and have been found in the lochs of Scotland. The freshwater lets them shake off the crustaceans, and then they swim back into the sea. They're really, really strange.

From the Greenlands Shark's point of view, it had been swimming around in the deep ocean for a couple of centuries when suddenly, the water started getting warmer. Then plastic appeared everywhere. Finally, on a single day, it felt thousands of shockwaves coming from everywhere. After that, the plastic gradually went away and the water went back to normal temperature, and the greenland shark swam around for a couple of centuries more, wondering what the hell that was.

The Greenland Shark is my personal favorite shark and fish in general. Their incredibly long lifespans gives them a sense of agelessness.

[@Dusenflugzeug]

I can agree, they are really cool sharks, and are also in my top 5 favorite fish. My favorite fish has got to be the gulper catfish though, as they have such a unique biology, and they look like they belong in the deep sea, even though they reside in the rio negro. Gulpers are so unique, as they can eat fish twice their own size, and they are able too because of their expandable belly, much like an angler fish. They are also very strong and of course, nocturnal… i guess that’s why they remind me of a deep sea creature so much. I actully had a gulper catfish, and he was my first fish. I was so fascinated by their biology that I spent hours just watching him swim around. Also, it is so interesting How Greenland sharks live up to 500 years or more, though.

[@alexanderwelker4464]

@@Dcookies100 at best it's pseudoscience, the projections use the same modeling technology that have made the last 5 or so incorrect world ending projections. We've survived 3 global freezings and 2 global warmings at this point. We don't understand climate, we can barely predict the weather, a control model was once significantly off from where it was supposed to be due to an error in the data equal to the flapping of a butterflies wings. It is unknown if CO2 has a net warming efect as it effects many various things. It causes major plant growth which has a cooling efect, and it promotes Ozone growth wich blocks harmful radiation coming from the sun that would kill us otherwise. Also the climates natural state is that of change, the planet used to be significantly hotter, where human life could only possibly survive at the poles. A time where the poles weren't frozen. We've also had several warming projections proven to be literal lies through cherrypicking the warmest areas and ignorimg the coldest areas to allow for a them to claim warming globally when the actual average was the same at the time the data was taken. Arrogance and political partisanship keeps these climate theories from being effectively challenged by already known data that contradicts them. I've only listed the tip of the iceberg. It's unscientific calling it pseudoscience is being charitable. How about instead of losing our minds about things we can't yet understand we focus on real tangible problems like waste polution for example. Instead we've turned a likely beneficial molecule into a boogey man and ignore the fact that we give China our waste who then dumps it with reckless disreguard for nature. We even demonize the cleanest form of energy that produces the most energy, nuclear power.

Before watching I'm gunna guess that it's because of two main reasons, one being that the bigger a creature is, the more room it has to grow stuff that combats the immense pressure. The second being that bigger creatures tend to have longer lifespans and thus more time to find a mate and reproduce in the vast nothingness down there. Adding onto the latter, bigger creatures tend to take more time to develop and be independent, so with less predators they have the opportunity to grow a bit slower

Marine Snow may be the most common but there are other sources of energy/nutrients in the deep in the form of geothermal vents and cold seeps. Geothermals are fairly well known, essentially underwater volcanoes, and will form dense colonies of creatures around them. Less well known are cold seeps, where methane and other natural gasses are being releases, which creates communities of organisms who are adapted to make use of it.
